Early pregnancy

Claudia • Mummy to William James 8th March 2015
I understand that doing a pregnancy test is the only positive way that can give you definite yes but...
​I am about 3 days late on my period and I was last month as well then had a very light abnormal period. I have been feeling dizzy and lightheaded, completely gone off my favourite food and I have been having a cystitis like feeling when going the bath room for the last two weeks. I know it isn't a water infection because it isn't all the time. 
​We have been trying for a baby for 4 months and I just don't want to get my hopes up. But are these signs?
